After creating one, you want to move the overlay by using the “@overlay _____ shifts to x y” command
Use the overlay tool so you can find the coordinates you want your overlay to move to.
If you want the overlay to move to that set spot in a specific amount of time then use:
“@overlay ______ shifts to x y in [s]”.
Sorry if any of that sounded confusing, if you don’t understand I’ll try explaining again.
